There aren't any bits in the genome there are nucleotides in them.
If you mean: if you represent the string of nucleotides using bits in an encoding where two bits represent each nucleotide (such as 00 = C, 01 = G, 10 = T, 11 = A) then why don't you just bloody say so instead of pointlessly shouting bits like an idiot?
I thought I did say that. But if anyone didn't understand what I meant by "bits" in the context of a discussion of information theory, and were too lazy to look it up, then they are free to ask me instead of, what's the phrase? "pointlessly shouting" that I'm wrong.
I might, of course, wonder why they were trying to derail the thread, given that we're meant to be talking about something else, but I would swallow this objection and explain to them what a "bit" is. And then refer them to the actual topic.
